TUBE-CLEANER.

SPECIFICATION forming part of Letters Patent No. 361,389, dated April 19, 1887.

Application led October 11, 18H6. SerialNo. 215,940. (No model.)

yTo all whom it may concern.-

Beit known that I, I sAAo A. WooDBUEY, of Cambridge, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Tube-Cleaners, of which the following, taken in connection with the accompanying drawings, is a specification.

The object of my invention is to produce a durable and an effective tubecleaner, which can be used tov ream and scrape the interior of tubes, such as boiler, condenser, and gun tubes.

In the drawings, Figures 1, 2, and 3 repre sent, respectively, the tubecleaner in plan, side elevation, and front elevation.

The tube-cleaner is made preferably of steel, which, when finished, is properly tempered. V

The reaming arms 10 and 11 are respectively provided with the cutting-edges 12 13 and 14 15. The' scraping-arms 16 and 17 are provided, respectively, with the scraping-edges 18 19 and 20 2l. The scraping-arms 16 and 17 are also respectively provided with slots or ways 22 and 23, in which the reaming-arms 10 and 11, respectively, are free to move in radial plane toward the longitudinal axis of the cleaner. The reaming and scraping arms are secured together, so as to provide the screwthreaded stem 24, to which is screwed a handle necessary to operate the cleaner.

The reaming and scraping arms are so madebeing of spring-steel-that when in use they are held against the interior circumference of the tube by the force due to their spring action.

In using the cleaner it is compressed sufciently to enter the tube to the size of which the cleaner is made. It is then forced forward and back, so as to thoroughly scrape the tube. If in the tube being scraped a. hard incrustation is found, then the tube-cleaner is rotated after the manner of reaming, the result being the perfect cleaning of the tube.

A tube-cleaner'of this invention is intended to be superior to others now in use in its simplicity and durability of construction and its effectiveness in use. Y

Two or more s'ets of scraping and reaming arms can be used, if desired.

What I claim as new, and desire to secure by Letters Patent, is-

In a tube-cleaner, the spring scraping-arms 16 and 17, provided withscraping-edges and with slots 22 and 23, in combination with the spring reaming-arms 10 and 11, provided with cutting-edges, all adapted to operate substantially as set forth.

In testimony whereof Ihave signed my name to this specification, in the presence of two subscribing witnesses, on this 4th day of October, A. D. 1886.

ISAAC A. WOODBURY.
